MOF gels with intrinsic emission color are prepared with 5-boronoisophthalic acid and Eu3+, Tb3+, and/or Dy3+. Single-metal gels exhibit trichromatic fluorescence, so full color emissions are readily obtained by tuning the type and/or ratio of Ln3+ ions to prepare mixed-metal gels. Nano-ribbons form from the precursors and then entangle together to generate the gels.
